Question

Find all values of x x

where f\left(x\right) < 0 .

XXXYYY-11-11-11-1-1-1-6-6-6

Step-by-Step Solution

To determine where the function f(x) f(x) is less than 0, observe the graphical representation:

  • The roots are located at x=11 x = -11 , x=6 x = -6 , and x=1 x = -1 . These are the x-values where the function intersects the x-axis.
  • Considering the general behavior of quadratic functions, the function is negative between the outer roots unless it passes through below x-axis at multiple roots due to shape.

The given graph suggests the function dips below the x-axis between x=11 x = -11 and x=1 x = -1 , passing through x=6 x = -6 .

After analyzing the intervals:

  • The interval to the left: x<11 x < -11
  • The interval to the right: x>1 x > -1

Therefore, values of x x for which the function f(x) f(x) is less than 0 are x>1 x > -1 or x<11 x < -11 .

The correct choice is: x>1 x > -1 or x<11 x < -11

Answer

x > -1 or x < -11
